Is God Really Interested in Healing Prayer?

Van has a debilitating diagnosis and need of healing. An older man in the church community offered to pray for him. Van's words not mine was the worst prayer I have ever heard. He said something happened, my chest began to burn. And then this guy just says, amen,. And the burning went away. The surgeons at the operating hospital don't believe them. They say they must have misdiagnosed van. So he goes into surgery that cut him open, no infection.
